HENRY BRADLEY, OF CAULFIELD, NEAR MELBOURNE, VICTORIA, AUSTRALIA.

MEANS FOR lDISINFECTING SANITARY FANS AND THE LIKE.

To aZZ whom it may concern.

Be it known that HENRY BRADLEY, a citizen of the Qommonwealth ofAustralia, and resident of Payne Street, (Jaultield, near lvielbourne inthe State of Victoria, Com monwealth of Australia, has invented acertain new and useful. Improved lVIeans for Disinfecting Sanitary Pansand the like, of which the following is aspecification.

This invention relates to improved means for disinfecting sanitary pans,commodes and the like and has been devised in order to provide cheap,simple and effective mechanism, the objects of which are hereinafterdescribed.

The essential characteristics embodied in the invention are asfollows 1. The use combined with a closet seat cover or lid of adisinfectant reservoir extending if desired the width of the seat aboutits pivot and means for. delivering predetermined quantities of thefluid, such means being characterized in that the reservoir isconstructed in two parts being preferably cylindrical and formed withsealed watertight ends having projections or pins which form the pivotpoints of the seat and consequently the disinfectant fluid reservoir.

2. The disinfectant fluid reservoir is provided with a substantiallylong feed tray and in communication with which is a retaining chamberfor predetermined quantities of disinfecting fluid, the position of theparts being such that on the raising of the seat cover, a predeterminedquantity of disinfectant fluid is displaced over the tray into theretaining chamber which is provided with a delivery pipe adapted on thelowering of the closet cover to deliver such predetermined quantity offluid into the pan.

8. The formation of the tray with a projecting flange along its upperedge. such flange at the ends inclining upwardly; thus at the ends ofthe tray an opening is provided between the divided compartments of thereservoir.

et. The provision at the ends and top of the tray of holes to allow therear division of the reservoir to drain through into the fluiddisplacement division in which the fluid is spread over the tray intothe discharging receiver below or at the rear of said tray, thusallowing of the displacement and discl'iarge of the whole of the fluidin the reser voir, the position and size of the said holes Specificationof LettersPatent.

preventing the quick return of the fluid to the rear compartment of thereservoir.

'closet or commode is positioned.

In order that this invention be more readily understood it will now bedescribed with reference to the accompanying drawings in which Figure 1is a perspective view of the apparatus, applied to a portable closet orcommo c.

Figure 2 is a perspective view of the apparatus.

Figure 8 is a modification of the bracket upon which the cylinder may bemounted.

The preferredmeans for discharging predetermined quantities ofdisinfectant fluid into the closet or commode pan aftereach use,consists of a cylinder 1 having detachable flanged and packed ends 2 soas to provide a water tight reservoir for the disinfectant fluid. Theseend caps 2 are centrally formed with outwardly projecting pins 3 whichare received by brackets 4 on a board 4 at the rear of the closet seatframe so providing a pivot for the reservoir and consequently the seatcover or lid 5 to which it is attached by forwardly extending brackets6. V

The reservoir 1 is divided into two compartments by a tray 7 whichextends vertically as shown in Fig. 6. The tray '7 carries at its rearupper portion a fluid-retaining chamber 8. The tray is formed with upturned flanges 9 and holes 10 and 10 at its opposite ends. The holes 10and 10 permit the disinfectant fluid to drain from the rear into thefront compartment of the reservoir and the flanges 9 direct the fluid.when the cover 5 is lifted, toward the opening 12 provided at the top ofthe tray. through which opening the fluid passes into the chamber 8.Leading from the discharging and retaining chamber 8 is a pipe 13 thatpasses at the ends of the tray Tot the two holes 10 through thereservoir and another connecting discharge pipe 14 externally of thereservoir connects at right angles with the pipe 13, stop s crews 15 and15 being provided on both pipes near thejoint gfOI' cleansing purposes.Along the discharge pipe 14 and near its discharge end is a smallchamber 16 so constructed as to receive the discharged fluid from thedischarge pipe 14 and this chamber 16 tapers outwardly with closed outerand inner ends 17 and 17, a hole being formed in the discharge pipe 1anear the inner end of. this tapered chamber which at its outer or widerend on its *underside is provided with-a discharge orifice 19 so thatthe fluid will *run into the empty chamber and discharge into the panwhen theseat lid is lowered. -The out-talre discharge pipe 14: issulficient inlength and extends past the hole where it dischargesintothedelivery chamber 16 to allow of an air cushion by means of closing "theend of the discharge pipe 14 to preventthe action of the air, on the lid5 being raised, from throwing out a bubble or The reservoir is fitted tothe brackets 6 connecting *the seat lid 5 and through a portion of thebrackets 6 from a high fluid level, are two air =pipes20 which lead fromthe reservoir so as to allow the out ifiow of air asthe reservoir andlid are in *movement and to faci'litate the flow of the fluid, while atthe top of the reservoir isa filling plug 21.

An essential characteristic is the position and 10 which allow o l? theflow from the one side of the tray to the-other and also al lows of thewhole of the chamber to be cleaned out of disinfectant if so desired be(fore rechargin and these holes are sufli- -cie11tly small to preventthe return of the fluid from the tray to the rear portion of thereservoir on any movement of the seat lid or cover.

The'closet to which the invention is adapts ed maybe portable or fixedand of any suitable size. 1

V In operation when the lid 5 is raised the reservoir is also partiallyturned on its pivot automaticallyand a predetermined quantity of fluiddelivers from the tray "7 into the receiving chamber 8; when the seatlid or cover 5 lowered afterusage, the fluid in the receiving "chamber8leads oil bygravity into "the delivery pipes 13 and 1a to thesm alldischarging chamber 16, thence by gravity into the painthe delivery pipe1 1 and discharge chamber 15 being preferably positioned in the lid orcover5 which at'the discharge point is cut away at 24 to allow the fluid'to run into the pan and the cycle is continued.

In the modification of the bracket as shown in Figure8, it will beseen-"that, avhen the pins 3 are inserted in the eye'23, the cylindercannot be removed from the platform unless the above mentioned bracketis unscrewed or otherwise detached from the platform.

This modification will be particularly useful in railway stations orschoolsor in fact, anywhere where persons are liable to inter- "lerewith the apparatus to the detriment of its future operations In theillustration more particularly illustrated. in Figure 1, the inventionis applied to a closet seat or commode which is adapted to be placed inthe room, the combination being provided with a vent to carry" thecompartment '24 in order to give free ac cess to the pan26and sand tray29.

IA flue pipe 31 is provided, being placed conveniently so that alldeleterious 'odours that may arise from the pan are carried away from:the building in which the apparatus is installed.

The apparatus shown in Figure 1 is jse cured to the seat'25 by screwswhich 'pass through the board 1 into the rear of the seat or cover 25.The pipe 14 leads into the seating portion 32, and the operation herein"before described takes place.

I desire it to be understood that various modliicatlons and Improvements'may be embodied without departing "from the spirit and scope ottheifunctions above described. What I claim as my invention and desire tosecure by Letters Patent is 1. The combination with acominode,"comprising a casing, a receptacle therein,'and a seat coverfor said casing, of means for hingedly connecting said seatcover to theseat of said commode, comprising a reservoir for disinfecting fluidattached to said seat cover and means pivotally connecting saidreservoir to said seat, andmeans within said reservoir whereby apredetermined quantity of said fluid will be discharged into saidreceptacle eachtime the seat cover is raised and lowered.

2. A construction as setforth in claim 1 including a pipe extending fromsaid'reservo r through which said predetermined quantity offluld 1Sdischarged into said re ceptacle, the free end of said pipe being closedand said pipe'being provided with a discharge orifice located adjacentto but at a sufficient distance from said closed end to provide an airpocket between said orifice and closed end to prevent an air bubble ordrop of fluid from being thrown from said discharge pipe as the seatcover is raised.

3. A construction as set forth in claim 1 wherein the means Within thereservoir comprises a tray dividing the reservoir into two chambers anda retaining chamber into which said tray is adapted to discharge aquantity of fluid when the seat cover is raised and from which the saidfluid is adapted to be discharged when the seat cover is lowered.

4;. A construction as set forth in claim 2 in which the discharge pipecarries near its outer end a small chamber into which said dischargepipe discharges the fluid through said orifice and from which the fluidis discharged into said receptacle through a cor responding orifice.

5. A construction as set forth in class 1 wherein the seat cover issecured to said reservoir by means of brackets provided with air tubestherein leading into said reservoir.
